This is achieved by a bleaching process that uses a solution of alkaline peroxide and detergents to clean and bleach the fabric to an excellent absorbent white color.

Visit our coaching middle, where you possibly can view movies on a range of applications from meals security to microbiology. We use gamma irradiation primarily for molded tube products, like dry transport tubes, because these products are much less permeable than the pouches and would not be as completely sterilized by ETO. Both the products and packaging tolerate the ETO process higher than they'd an autoclave or radiation sterilization process. ays are a form of electromagnetic radiation—like x-rays, however with higher vitality.
